devtool: upgrade: workaround for recipes which apply patches conditional upon class

If we're upgrading a recipe that appends additional patches for, say,
class-native, and we're just upgrading the target variant, then when we
copied the recipe into the workspace we skipped copying the additional patches
for the native variant. This caused warnings because the workspace
recipe is preferred. Look at SRC_URI for all variants when copying files
to work around this.

More work is needed to make it easier to work with recipes that use
BBCLASSEXTEND where you need to build more than one variant at once, but
this at least fixes the immediate ugliness.
